US singer and actress Demi Lovato has collaborated with DIFF Eyewear to design her own sunglasses collection, which will benefit nonprofit organisation Eyes on Africa.

For each pair of glasses sold, the brand will donate a pair of reading glasses to someone in need, and DIFF Eyewear took to Instagram to share the news, posting 'We're so grateful that this partnership with Demi Lovato has allowed us to expand our charitable outreach by continuing to provide reading glasses to people in need with each pair of sunnies purchased'.
